Hello everyone!
I have strange problem.
I have plc, inverter (mitsubishi), incremental encoder (sick) and motor.
When i set the frequency on the inverter about 1,5Hz, the plc correctly counts impulses, but every higher frequency causes the plc counts impulses incorrectly or doesnt count.
All the parameters of high-speed counters and PLC program i am sure there are right ( i'm using only instruction to start high-speed counting (HIOEN) and to enable interrupt (EI).
Type of encoder - A/B phase, HTL.
PLC - FX5U
PLC program - Gx works 3.
Maybe somebody had similar problem? Maybe somebody could tell me where i need to look for the solve?
Thanks for help!
